Gems you might not know about

Security

schroot

Manpage: "Securely enter a chroot environment. schroot allows the user to run a command or a login shell in a chroot environment. If no command is specified, a login shell will be started in the user’s current working directory inside the chroot."

Network

netem/tc

Website: "netem provides Network Emulation functionality for testing protocols by emulating the properties of wide area networks. The current version emulates variable delay, loss, duplication and re-ordering."

examples:

# add a default delay of 100ms
tc qdisc add dev eth0 root netem delay 100ms
# random delay between 10ms and 100ms 
tc qdisc change dev eth0 root netem delay 100ms 10ms
# duplicate 1% of the packets
tc qdisc change dev eth0 root netem duplicate 1%

can be used as a LART.

X

synergy

"Share mouse, keyboard and clipboard over the network" - you only need one mouse + keyboard to control several desktops w/ displays.

Synergy is a very good alternative to x2x/x2vnc. It features Windows, Linux and MacOS clients and does a bit more than x2x or vnc. It can not only share your clipboard to all machines attached, but also disable all screensavers/locked screens at once.
